Yang S.L., Li M., Dai S.B., Liu Z., Zhang J., and Ding P.X. The condition of wetlands reflects a combination of physical, chemical, and biological attributes. Moreover, developed areas will often be protected with bulkheads, dikes, and other structures that keep new wetlands from forming inland. Other important steppe birds find refuge here, such as the Great Bustard (Otis tarda) or the White-headed Duck (Oxyura leucocephala). 2012. The Great Lakes watershed has lost 62 percent of its original wetlands, and some parts of this region have lost more than 90 percent of these habitats. Serious consequences have already been caused by the coastal wetland loss, such as coastal flooding, erosion, and biodiversity decrease. Without wetlands, cities have to spend more money to treat water for their citizens, floods are more devastating to nearby communities, storm surges from hurricanes can penetrate farther inland, animals are displaced or die out, and food supplies are disrupted, along with livelihoods. Understanding the relationship between landscape and the dynamic nature of wetlands is essential to the assessment of wetland functions and values.

For many years now, conservationists have specially selected and protected certain species in the hope of preserving biodiversity. By combining conventional engineering with ecosystem-based engineering, we may mitigate potential big flooding risks in the long run (. . Wetlands are ecosystems that are periodically or permanently flooded with shallow water. Although the area of coastal wetlands is rather small compared to many other terrestrial ecosystems, their productivity is comparable to the most productive ecosystems. The landfills discharge various kinds of chemicals on the land adjacent to forest, various natural habitats, and water systems such as underground and surface water which makes the environment unappealing to the survival of trees, vegetations, animal and humans. 0000008710 00000 n On this regard, degradation means damage or reduction in quality of environmental features, primarily influenced by human activities. 0000060887 00000 n It is caused directly or indirectly by anthropogenic activities that extract various environmental resources at a faster rate than they are replaced, and thus depleting them. USA. Natl. Improve the health of wetlands by planting a buffer strip of native plants. These anthropogenic activities simply alter the natural process combined, thus, destroying the natural ecosystems supporting biodiversity. According to theBrookings Institute, restoration of the Great Lakes will create economic benefits of at least $50 billion and create thousands of jobs.

Embedding ecosystem services in coastal planning leads to better outcomes for people and nature. Second, the reduced freshwater inflow allows saltwater encroachment, which kills the fresh . They provide refuge and stopover sites for millions of migratory birds such as cranes and storks. Human uses of wetlands, such as drainage for agriculture and filling for industrial or residential development, can impose irreversible impacts to wetlands. It is important to recognize to what extent various disturbances affect wetlands when assessing disturbance and impact, and when considering wetland protection options (Clearwater et al., 1998). The act of deforestation (cutting down of trees) has impacted on the world in terms of depreciating the natural environment and wildlife. Front. Besides the foul smell from the landfills and periodic burning of the wastes make living in such environments unbearable. (Mitsch and Gosselink, 1993). The evolution of embryonic creek systems in a recently inundated large open coast managed realignment site, Coastal wetlands mainly include ecosystems of mangroves, coral reefs, salt marsh, and sea grass beds. Geophys. Along tidal rivers and in extremely flat areas, floods can be caused by storm surges from the sea or by river surges. Natural events such as wildfires, hurricanes, landslides, tsunamis and earthquakes can totally lower the survival grade of local animal communities and plant life in a region. But the production of Chinese fishery is mainly from aquaculture (>70%) (, Coastal wetland reclamation often results in the destruction of spawning and nursery ground for many marine species, while birds lose their food and shelter with more disturbed habitats. What are 3 major causes of degradation and loss of wetlands? Major role of marine vegetation on the oceanic carbon cycle. Ramsar Convention Secretariat, Gland, Switzerland. 2010. 2017.

Salt marsh restoration experience in San Francisco Bay. In part, this has been a result of natural evolutionary processes, but human activities, such as dredging wetlands for canals or draining and filling for agriculture, grazing, or development, share a large part of the responsibility for marsh habitat alteration and destruction. Human activities can also increase the extent of wetlandsfor example, by creating shallow ponds or re-establishing formerly drained wetlands on farmlands. Coastal squeeze is the concept proposed to describe coasts without retreating space facing sea level rise (, Wind waves also play an important role in the erosion and loss of salt marshes worldwide, especially at boundary zones (, Loss of wetland area means the loss of its corresponding ecological services for human beings (, In southeastern Asia, great destruction has been caused by flooding with reduced or no protection from mangroves and salt marshes, as seen in Bangladesh, Thailand, the Philippines, and Indonesia (, The world fishery capture and aquaculture production has been increasing steadily since the 1950s, among which, the contribution from China has been prominent since the 1980s. 0000018452 00000 n Wetlands' highly developed root systems hold the soil in place and filter pollutants, naturally improving water quality (including water that is eventually used for drinking).
